Electromagnetic flowmeter online inspection method introduction description

The electromagnetic flowmeter is a flowmeter with high precision, high reliability and long service life. Therefore, we are very careful in every aspect of designing product structure, material selection, process development, production assembly and factory testing. China's most advanced production equipment dedicated to electromagnetic flowmeters and flow flow calibration devices ensure the long-term quality of products in both software and hardware. The electromagnetic flowmeter is specially designed with a Chinese liquid crystal display with wide backlight and wide temperature. It is complete in function, intuitive in display, convenient to operate and use, and can reduce the inconvenience caused by the English menu of other electromagnetic flowmeters.
On-line inspection method of electromagnetic flowmeter commonly used at home and abroad: On-line verification method of large-caliber electromagnetic flowmeter In the 1990s, Shanghai Waterway System began to explore online inspection and verification. They used a dedicated analog signal detector to detect the converter, and the sensor inspection To test the electrode connection resistance.
The meter is a flow meter with on-site display volume flow or implantable density to display mass flow. It does not need to be equipped with secondary instrument. It can switch to display cumulative flow and instantaneous flow, and can be powered by the internal battery of the instrument. No external power supply is required. Suitable for oilfields or places with inconvenient power supply. The flowmeter measures the flow of liquid, gas and steam in ø25-300mm (inside diameter) pipelines. When used in hazardous locations, the intrinsically safe explosion-proof structure should be selected.
Check the excitation coil including the insulation resistance and copper resistance of the excitation connection cable, as well as the indirect method of checking the excitation current of the converter output and checking the magnetic field strength. In the pipeline with the stop flow condition, enter the hole from the vicinity of the sensor, check the electrode and lining for contamination, deposition and clean. It is the main type of speed flow meter, which uses a multi-blade rotor (turbine) to sense the average flow velocity of the fluid, and derives the flow or total amount of the meter. It consists of two parts, the sensor and the display, and can also be made into a unitary type. Generally used for gases or liquids that are free of corrosive, dust-free or particulate components.
